SANITARY I /IILK-CAN COVER.

Specification of Letters Patent.

Patented Aug. 8, 1916.

Application filed June 23, 1915. Serial No. 85,879.

T 0 all whom it may concern:

Be it known that I, ERNST KREUTZBERG, a citizen of the United States, residing at rilhambra, in the county of Madison and State of Illinois, have invented a new and useful Sanitary Milk-Can Cover, of which the following is a specification.

This invention relates to sanitary covers or closures especially designed for use in connection with milk-cans and the like.

An object of the present invention is to provide a sanitary milk-can cover that may be readily applied to the standard milkcans to exclude all extraneous matter that would deleteriously affect the milk, but, at the same time to allow a free circulation of air within the milk-can to assist in cooling the milk and removing objectionable odors which frequently accompany closed milk receptacles.

Another object of the invention is to provide a sanitary milk-can cover that yieldingly but firmly engages the milk-can to effectively minimize the probability of its accidental displacement.

A further object of the invention is to provide a receptacle cover, a closure of general improved construction, whereby the device will be simple, durable and inexpensive in construction, as well as convenient, practical, serviceable and eflicient in its use.

l/Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiments in the accompanying drawings, wherein Figure 1 is a vertical sectional view of the invention shown applied to an ordinary millecan. Fig. 2 is a top plan of the invention, a portion being shown in section. Fig. 3 is a bottom plan of the invention. Fig. 1 is a detail sectional view taken on the line M of Fig. 1. Fig. 5 is a detail sectional view taken on the line 55 of Fig. 1.

In carrying out the present invention there is provided a frusto-conical member 1 which rests upon the beaded top T of an ordinary milk-can C, which is provided with the usual restricted neck N. A depending rim or annulus 2 is rigidly secured to the periphery of the frusto-conical member 1 to surround the top T of the can C in order to pre vent lateral movement of the cover relative to the top T of the can C. An upstanding annulus or flange 3 is formed at the upper terminal of the frusto-conical member 1, the function of which will be hereinafter disclosed. in. order to allow a free circulation of air within the can and at the same time exclude all extraneous matter, there is provided an upright perforated or foraminous cylindrical member 4 which is secured to the frusto-conical member 1 adjacent but spaced from the upstanding flange 3. A convex cover 5 is secured to the upper terminal of the perforated cylinder 4 and extends radially beyond the perforated cylinder 4L, as indicated at 6.

There is provided a resilient securing member 7, which comprises an intermediate arcuate portion 8 and substantially perpendicular arcuate arm 9, which terminate in angular securing feet 10, that are slidably received by sockets 11 which are in turn rigidly secured to the inner face of the frusto-conical member 1. Each socket 11 comprises a base plate 12 which is provided with opposed overhanging flanges or members 18. The inner or adjacent terminals of the plates 12 are provided with lips 14 which are adapted to be bent behind the angular feet 10 and against the arm 9 of the resilient securing member 7 to hold the angular feet 10 against longitudinal movement, thereby rigidly securing the entire securing member 7 to the frusto-conical member 1.

In practical use the improved coveris applied to the milk-can C, by simply exerting pressure inwardly upon the cover, which causes the resilient securing member 7 to first engage the flaring top T of the can C. As additional pressure is exerted upon the cover, the arms 9 are forced toward each other by their engagement with the flaring top T. The arms 9 are permitted to yield toward each other by the corresponding flexing of the intermediate portion 8 of the securing member 7. Finally the inner face of the frusto-conical member 1 engages the beaded edge of the flaring top T. at which time the arms 9 will resiliently but firmly engage the restricted neck N, thereby holding the improved cover securely upon the milk-can C. The milk-can, now, is obviously closed against the admission of any deleterious extraneous matter and, also prevent intrusion by domestic animals, rodents, fowl, insects or other pests, but, however, the receptacle is open to the free admission of air to assist in cooling the milk and removing objectionable odors. Falling rain is, also, obviously excluded from the milk receptacle and the rain Water that would tend to enter the milk-can by capillary attraction is barred by the upstanding flange 3.

Having thus described my invention, What is claimed as new is 1. In a device of the class described including a cover having an aperture; a per forated member surrounding the said aperture; a supplemental cover secured to the said perforated member; an upstanding annular flange formed about the said aperture and Within the perforated member, said flange being adapted to prevent the entrance of extraneous liquids through the said aperture by capillary attraction.

2. In a device of the class described including a cover having an aperture formed therein; a perforated member secured to the said cover and surrounding the said aperture; a supplemental cover secured to the perforated member; attaching plates secured to the said cover; opposed overhangs extending from the said attaching plates; a resilient securing member; and means for attaching the resilient securing member to the said attaching plates.

3. In a device of the class described ineluding a cover having an axial aperture; a perforated member secured to the cover and surrounding the said aperture; a supplemental cover secured to the perforated member; an upstanding annular flange formed about the said aperture and adapted to prevent the entrance of extraneous liquids through the said aperture by capillary attraction; attaching plates secured to the said cover; opposed overhangs formed on the said attaching plates; a resilient securing member; and means for attaching the securing member to the said attaching plates.

In a device of the class described including a cover having a concentric aperture; a perforated member surrounding said aperture; a supplemental cover secured to the upper terminal of said perforated member; attaching plates secured to the cover, said attaching plates having opposed overhangs and inwardly extending lips; a secur-.

ing member comprising a resilient intermediate portion, resilient arms extending substantially perpendicularly from said intermediate portion and securing feet extending angularly from the resilient arms, said securing feet being adapted to be slidably received by the opposed overhangs and held rigidly therebetween by bending the said lips behind the securing feet.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of tWo Witnesses.
